To all whom it may concern: I

ject of the German Emperor, and resident of Hartmannstrasse 6, Augsburg, Germany, have invented certain new and useful Imof Fluids, of which the following is a speci 'cation.

The invention relates to an apparatus for the electrolytic treatment of fluids, which is s eciall adapted for the production of b feach iquors, and has for its object first to increase the product for the electrical energy expended, and further to produce a greater yield from the raw material such as salt used.

It is well known that bleach liquors on account of their strong corrosive action can only be manufactured in vessels made of certain materials, and that during the electrolysis the electrolyte itself isstrongly heated. (.are has therefore to be taken in the manu- ".acture of such vessels to make use of the cheapest materials which can be used such as cla or burned alumina, and during the electro ytic process to cool the electrolyte.

In the present invention the desired object is attained by leading the electrolyte through a cooled coil made from clay arranged horizontally and situated in a cooling chamber. The upper parts of the windings discharge into chambers in which the electrodes are so arranged that each chamber has a positive and;; a negativepole. Each winding of the cooling coil joins two chambers, so that the solution enters the first chamber and is here electrolytically treated, and then passes through the. first winding of the coil being at the same time chamber, where it is again-submitted to electrolysis. The solution next asses through the second winding of the coi and is thereby again cooled and then enters the third electrolytic chamber. And so the process of electrolysis and cooling is alternately repeated untilthe liquid has passed throughall'the chambers and all the windings. The number and size of electrolytic chambers and the dimensions of the coil windings depend upon the quantity of fluid to be treated and the electric energy available;

By means of the present invention it is possible with a com aratively small apparatus when the electro yte is sufiiciently cooled to produce an especially high in fact any desired concentration of electrolyzed liquor without passing the fluid, several times vessel being shown in section, Fi

and a suitable support for the through severalapparatuses. In the drawing two forms of construction of the new apparatus are shown;

The bent. carrier 4ziconsisteifir ing of suitable conducting'm'aterial has at its.

bend one or more feet 5 and at the endzofthem -two arms feet 6 and 7. The carrier 4 has also holders 8 for the electrodes 9; the latter can be made from any material-suitable for the purpose and may be manufactured in any suitable form. For instance electrodes of hardened lead with a core of copper, or electrodes of platinum or carbon can be used.

The carrier 4 rests with its feet 5, 6, 7, in

notches 10 in the upper edge of the cooling vessel and the feet 5, 6, 7 are so long that the carrier 4 is completely out of contact with the '60 the apparatus 3 shows a 65 Fig. 6 is a side view of the 70 a connectinglso "fluids the a e beingmade of suitable material and'adapted partitions 3 and'thcrefore the chambers" the one-arm forming arm forming the negative The electrodes supported by I for instance the }positive le di 'into the solution of the one o amber, while t e electrodes supportedby the other le dip into the solution'of thenext chain '1'.
